Error in DIAMOND_analysis_counter.py

[McKSal]

Hello, I am having issues with DIAMOND_analysis_counter.py script
I am getting a similar error as in this previous post #57

command:
python Diamond_analysis_counter2.py -I BMRNA2_other_nr.daa_viewable -D /media/scratch/2022_diamond_nr_db/nr -O BMRNA2_other_nr_organism

error:
Now reading through the m8 results infile.

Analysis of BMRNA2_other_nr.daa_viewable complete.
Number of total lines: 426637
Number of unique sequences: 422738

Starting database analysis now.

From post linked above:
"the parsing script doesn't do well when there are multiple instances of square brackets in the line."

When I go in and look at the line (151) all I see is the string of AA's:

Hi McKSal,

Sure, let's see if I can help. I might need to ask a couple questions and have you try a couple things.

First, don't worry about the line 151 - that's the line in the Python script that's throwing the error, not the line in the input file.

The error that you're getting is when the script is trying to read in the nr database. There's some line in there that's giving it trouble because it can't seem to split it into the ID, organism, and functional names.

I don't have it print out a count by default of which line in the database causes it to error out; that would be a good item for me to add, since it would provide a bit more debugging information. Do you feel comfortable making a couple small edits to the Python script and then running this again?

If so, you could replace lines 161 and 162 in the DIAMOND_analysis_counter.py script with the following:

if db_org[0].isdigit():
	split_db_org = db_org.split()
	try:
		db_org = split_db_org[1] + " " + split_db_org[2]
	except IndexError:
		print(line)
		print(str(db_line_counter))

When you rerun the script, it will still fail in the same place - but this time it will print out the offending line from the database that's causing the issue, as well as the count of which line in the database this is.

That should give me more information so I can recommend a solution.
